Calculating speaker enclosure volume is a five step procedure.

(Make sure you do not forget to subtract the thickness of the wood that you

have selected to use to build your enclosure.)

Step One: Measure Height

Step Two: Measure Width

Step Three: Measure Depth

Step Four: Height x Width x Depth

Step Five: Divide the results that were in step four by 1728

12" x 12" x 12"= (1728 / 1728 = 1.0 cu ft.)

Complete formula should look like this

Height x Width x Depth / 1728 =__________

Below are illustrated versions of all the steps that you should take.

(FOR EXAMPLE ONLY)

Step One

Step Three

Side View

12"

13.5"

13.5-1.5=12

18"

19.5"

The wood that we are using is 0.75" thick

The 1.5 that you see in the formula is the thickness

of the wood.

Calculating thickness of wood:

Measure how thick the wood is then multiply by two.

The reason that you are multiplying by two is each

side of the enclosure.

Left + Right=1.5

Top + Bottom=1.5

Front + Back=1.5

0.75 x 2=1.50

18 x 2 x 12=2592

2592 / 1728=1.5

1.5 cu. ft. is the results for this enclosure

cu ft.

Step Two

13.5-1.5+12
